Ever wondered what's inside the Nerf target toy for kids?
It's basically a rubber-dome keyboard. Inside is an ASIC with a LCD and a speaker for sound effects.
Note: If you want to disassemble it, pay attention to the screws behind the stand!
#Project-Idea: add MCU with wireless connectivity for fun - I cannot do it, I don't own this target.
